Improving soil

We've been pottering around gardenning our flower borders for quite a long time, but have never done much in the way of putting anything back into the soil to improve it, short of emptying the spent contents of tomato grow bags (which are probably devoid of beneficial nutrients by that stage) around the beds.

For new borders I plough as much organic stuff in as possible....garden compost, manure, etc.....before planting.

In an established border mulching with generous quantities of compost is important. And when I remove a plant...to divide or discard....I put compost into the planting hole. Plus the use of organic fertiliser......fish blood and bone, chicken pellets, dried cow manure. I regularly mix garden compost or mpc with dried cow manure to feed both plants and soil
